            emissions  (25%  CO2,  50%  CH4,  75%  N2O  annually),  which  contributes  to
            deforestation and destruction of agricultural land to a great extent (Cassman
            et al, 2003; Tubiello et al, 2007).
               It was declared in the  UN Universal Declaration of Human Rights (1948) that
            access to food is a basic human right and in 1974, “World Food Conference”
            was held. The concept of food security raised in the conference was defined
            with a focus on supplies as “availability at all times of adequate world food
            supplies of basic foodstuffs to sustain a steady expansion of food consumption
            and to offset fluctuations in production and prices”. In the 2001 FAO report,
            however, the definition of food security was updated as “a situation that exists
            when all people, at all times, have physical, social and economic access to
            sufficient, safe and nutritious food that meets their dietary needs and food
            preferences for an active and healthy life”. Thus, the concept of food safety
            was included in the concept of food security. According to Committee on
            World  Food  Security  (CSFS),  food  security  has  five  basic  principles:  (1)
            availability, (2) access, (3) acceptability, (4) adequacy and (5) agency (CSFS,
            2015; Koç  and Uzmay, 2015).  However, climate change threatens these
            principles due to reasons including the decrease in the efficiency of plant and
            animal production, increase in food prices, decrease in food incomes, etc.
            (Koç and Uzmay, 2016).
               To avoid it, agro-ecological agriculture, which is an example to recent
            remedial agricultural practices, should be promoted. “Agroecology”, which
            has been institutionalized as a concept since the 1990s, is a concept that
            refers to the operation of agro-systems by providing sustainable agriculture
            through the use of biological, ecological, sociocultural, economic and political
            mechanisms, functions relationships and designs (Özkaya and Özden, 2021).
               Any assessment on the negative effects of climate change on agroecology,
            such as droughts, water scarcity, the change in product patterns etc. should
            be done within the changing socioeconomic framework of agriculture. Such
            assessments should focus on how to deal with climate change with a critical
            stance on issues such as the food security of rural population. In addition,
            it is thought that the important regional inequalities between developing
            and developed countries due to different agricultural and socioeconomic
            conditions will increase even further (Rosenzweig and Parry, 1994; Fischer et
            al, 2005; Tubiello et al, 2007).
               Another issue worth noting in literature is the fact that the product and
            pasture physiological responses to the climate change effects observed
            experimentally on land and farmland in rural areas are largely underestimated.
            Furthermore, it is also observed that the potential negative effects are largely
            undiscovered and this decreases the reliability of the regional and global
